Thanks for all the input guys
the level of play will be both high school and college....mainly college though. I will be shooting track and field, Soccer, and Baseball outdoors in daylight. I'll be shooting basketball and Indoor Track and Field inside. Football season is over until next year so I wont be taking many photo's at night. I may have a chance to take some photo's of Professional athletes at Track and Field Meets but I'll mostly be at local high school and college meets.
As far as where I'm shooting from. We don't have restrictions. We're pretty much right where the action is. Sideline for football, near the Baseline for Basketball, start and finish line for Track and Field, near the long jump, high jump pits etc.
